Rear differential recall replacement service
To anyone who had a defective rear differential replaced, did you get your car serviced after breaking in the rear diff? I ask because at 1,200 miles BMW changes rear diff fluid.
Thanks, Brian |

PS: mine was, but during the period it was mandatory, so the first diff never even got broken in. |

The diff fluid needs to be replaced at 2200 miles( 1200 miles after new diff put in). I still can't completely get on it to allow the new diff to "breakin". I did however have car on the track just before the old diff was replaced. There is some controversy on these forums about the M2 1200 mile breakin. Seems the M2 1200 mile breakin service is more for the M diff than for the engine. M235 doesn't have the same 1200 service IIRC! M3 and M4 do also but they may also undergo ECU reprogrammed to increase power and rev limit. It is confirmed that the M2, aside from Launch control in DCT, has NO ECU power or rev limitations removed at the 1200 mile BI service |

But as you said, the M diff if by far the most important part of that puzzle. |

So my car is getting the diff replaced now. I asked my service advisor if the 1200 mile break in service was required for the new diff and he said that it was, but I did not have to keep the car under a specified rpm/speed as that was for the engine only.

How is your car now? I just got my diff replaced under warranty and the SA told me that I have to re-do the break-in procedure again...
